To aZ whont it may concern Be it known that we, AUGUsTUs T. KNOB- ZERand-SIMON PETER DANNER, citizens of the UnitedStatesre'siding atMiddletown, in the county of Middlesex and State of Connecti SpEdge-Supporting. Hook, of which the following is a specification. 1 I

This invention relates generally-to spring bottoms'for furniture and thelike, and especially to means for fastening the springs relative to eachother and to the sides of the frame.

The object of the invention is to rovide T5 an improved fasteningwherein a fold of wire is "wound'about thepart to be fastened and theloop of the fold' passed between the side .A further object of theinvention is to-pro eral ipftiings and embodying our improved 103p j Ifurther object of the invention'is to pro I --vide.a fasteningfor-securing an edge bar to V the-outer edge of the topwhirl of theouter row of springs and embodying our improved further object of theinvention is to provide a pivoted fastening for securin the outer row:of springs to the edgeof the rame and embodying; our improved loop fold.

With these and other objects 1n view the present invention consists inthe combination and arrangement of parts, as will be hereinafter fullydescribed, and shown in the accompanying drawings.

In the drawings, Figure 1 is a top plan view of a spring-bottomembodying the invention.

Flg. .2 is a vertical sectional view of a single spring with theedge-s11 porting hook in position. Fig. 3 is adetal view of the spacingLike characters of reference designate corresponding parts throughoutthe several views. l

The basic feature of the inventionisanintegral fastening composed ofwire 'folded upon itself to form the loop 1. The loop 1 is Specificationof Letters Patent.

Patented March 20, 1906.

yvound' about the part to be fastened, as at '2, with the loop passedbetween the side wires and outstanding substantiallyupon the sideopposite.

-The invention is preferably applied by twisting orwinding the loop 1about a coil 3 of a spring adjacent the edge of the frame 4,

to which the s rings areisecured. The 'single ends 5 are ent at an angleat 6, forming alined pintles 7, secured to the edge of the frame 4, asby the staples 8.

Another application of the basic element is in 'a fastening 9 with theloop fold wound about the. outer side of the upper whirl of the outerrowof springs ,10 and the edge rod 11, securin the spring and rodtogether. The free'en s 12 are then Wound, as at 13, about the side ofthe whirl oppositethe edge rod.

' Anotherfapplication is in a fastening for spacvide a fastening forproperly spacing the se'v- I is folded first at the middle substantiallyat right angles, as at 1'4, and the single ends ing the several springsand wherein the wire again folded upon themselves and fastened,

as at 15. The middle fold of one fastening is then wound about. themiddle fold of the other, as-at 16, forming a jointed fastening The fourloops are then wound about the top whirl, as shown at 17, thus holdingthe several springs at the desired spacings relative to each other.

' By the several applications, as above noted,

a complete spring-bottom is produced, as

shown in'Fig. 1, from avie'w of which andthe foreoin description its'use and operation will ec? arly and fully understood. It will beunderstood, further, that the s ring-bottomassembled as above is-applicale to any form of bed, chair, car, or wagon-seat or to other uses whenspring-bottoms are or may be used.

Having thus described the invention, What is claimed is 1. In a deviceof the class described a plurality of coil-springs with their basessecured in a common plane, an edge bar connecting the center sides ofthe 'top whirls of the outer row of springs, a fastening composed ofwire folded upon itself and with the loop of the fold wound about theedge bar and the spring I in a common plane, a pair of coactingfastenings to hold the several springs properly spaced relative to eachother and each composed of a wire folded at the middle and each endagain folded upon itself and with the folds wound about the coils of thesprings and passing between the side wires and the middle fold offastening wound about the middle fold of the other.

3. A device of the class described, comprising a frame, a plurality ofcoil-springs, with their bases secured to the frame, an edge barconnecting the outer sides of the top whirl of the outer row of springs,a fastening composed of wire folded upon itself and with the loop of thefold wound about the edge bar and the spring and passing between theside wires and the single ends of the fastening wound about thespring-coil opposite the edge bar, and a fastening composed of wirefolded upon itself and with the loop of the fold wound about a coil ofthe outer spring below the bar and passing between the side wires andwith the single ends pivotally secured to the frame.

4. A device of the class described, comprising a frame, a plurality ofcoil-springs with their bases secured to the frame, an edge barconnecting the outer sides of the top whirls of the outer row ofsprings, a fastening composed of wire folded upon itself and with theloop of the fold wound about the edge bar and the spring and passingbetween the side wires and the single ends of the fastening wound aboutthe spring-coil opposite the edge bar, and a pair of coacting fasteningsto ,hold the several springs properly spaced and each composed of a wirefolded at the middle and each end again folded upon itself and with thefolds wound about the coils of the springs and passing between the sidewires and the middle fold of one fastening wound about the middle foldof the other.

5. A device of the class described, comprising a frame, a plurality ofcoil-springs with their bases secured to the frame, a pair of coactingfastenings to hold the several springs pro erly spaced and each composedof a wire fol ed at the middle and each end again folded upon itself andwith the folds wound about the coils of the springs and passing betweenthe side wires and the middle fold of one fastening wound about themiddle fold of the other, and a fastening composed of wire folded uponitself and with the loop of the fold wound about a coil of the outerspring below the top whirl and passing between the side wires and withthe single ends pivotally secured to the frame.

6. A device of the class described, comprising a frame, a plurality ofcoil-springs with their bases secured to the frame, a pair of coactingfastenings to hold the several springs properly spaced and each composedof a wire folded at the middle and each end again folded upon itself andwith the folds wound about the coils of the springs and passing betweenthe side wires and the middle fold of one fastening wound about themiddle fold of the other, an edge bar connecting the outer sides of thetop whirls of the outer row of springs, a fastening composed of wirefolded upon itself and with the loop of the fold wound about the edgebar and the spring and passing between the side wires and the singleends of the fastening wound about the springcoil opposite the edge bar,and a fastening composed of wire folded upon itself and with the loop ofthe fold wound about a coil of the outer spring below the bar andpassing between the side wires and with the single ends pivotallysecured to the frame.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
